Test Y - Safety Belt Warning Never/Always On
- If safety belt warning chime works properly, go to next step. If warning chime is not okay, see WARNING SYSTEM article.
- Turn ignition switch to OFF position. Check continuity across terminals of warning indicator bulb. If continuity exists, go to next step. If continuity is not present, replace bulb and retest system.
- Turn ignition switch to OFF position. Remove instrument cluster. See INSTRUMENT CLUSTER
under REMOVAL & INSTALLATION. Remove instrument cluster connector C249 on vehicles without tachometer (C253 with tachometer). Disconnect safety belt warning chime module connector. See Fig 1
. Measure resistance of Light Green wire between cluster connector and pin No. 10 of warning chime module connector. Measure resistance of Light Green wire between cluster connector and ground. If resistance is less than 5 ohms between cluster and module, and more than 10 k/ohms between cluster and ground, replace instrument cluster printed circuit and retest system. See PRINTED CIRCUIT
under REMOVAL & INSTALLATION. If resistances are not to specification, repair open or short in Light Green wire and retest system.
